Question

The velocity $(v)$ - time $(t)$ plot of the motion of a body is shown below:The acceleration (a) - time ( $t$ ) graph that best suits this motion is :

Accepted Answer

Sol. [Key Concept: Velocity–time graph — displacement and acceleration] Initially, the body has zero velocity and zero slope. Hence the acceleration would be zero initially. After that, the slope of v-t curve is constant and positive.After some time, velocity becomes constant and acceleration is zero.After that, the slope of v-t curve is constant and negative.
